Roms

Okay, so I figured out how to download ROMS...I think. I went to [removed] in my browser and it downloaded the file but when I got to open it in the emulator it is saying "Load Rom Failed. Please try another file? It is a zip file. Do I need something extra downloaded on the phone to unzip it? Sorry I am a noob to android phones. Help is much appreciated.
